LOS ANGELES (AP) -- A court-appointed attorney for Michael Jackson's children says a petition has been filed to appoint a temporary guardian. Margaret Lodise, the guardian ad litem for Jackson's three children, says a petition to appoint Tito Jackson's son TJ as a temporary guardian has been filed in Los Angeles. A request for an expedited hearing has been made, but it's uncertain a hearing will be held Wednesday. TJ Jackson is at a Los Angeles courthouse, along with attorneys for Jackson's estate. The filing comes after days of turmoil in the Jackson family, with matriarch Katherine Jackson spending several days in Arizona out of contact with her grandchildren. Katherine Jackson is the court-appointed guardian of her son Michael's three children, Prince, Paris and Blanket. The children have remained at the home they share with their grandmother in Calabasas. The house was the scene of a family disturbance Monday that sheriff's deputies continue to investigate.
